Cheap flights from London to Luxembourg

October is the cheapest month on this route, and fares stay reasonable either side of it, in late September and through November. Summer and the December holidays push prices up, when both capitals fill with visitors and business travel peaks. Midweek departures, especially Tuesday and Wednesday, usually undercut Friday evenings and Sunday returns. Book a few weeks ahead for spring and autumn trips, and keep an eye on the calendar for the months where the price dips.

Several carriers fly this route. British Airways and Luxair are the full-service names, and their fares usually bundle more. Ryanair, Easyjet and Wizz Air Malta are the low-cost options, where the ticket covers a seat and a small cabin bag and everything else is charged separately. KLM Cityhopper, KLM Royal Dutch Airlines, Lufthansa City Airlines and Scandinavian Airlines tend to show up on connecting itineraries rather than nonstop ones, so check the total journey time. Direct flights do exist between London and Luxembourg, so filter for nonstop when the journey time matters.

Luxembourg airport is the arrival point for this route, and it sits close to the city, so the transfer into the centre is brief. Buses and taxis run into town, and a taxi is the simplest option if you land late. On the London side, remember that your departure airport shapes the whole day: Heathrow, Gatwick, Stansted, Luton and London City all sit at different distances from the centre, and the trip to the airport can take longer than the flight itself. Check your terminal and leave room for the journey.

Country facts: Wikidata

• Check which London airport your fare leaves from, since Heathrow, Gatwick, Stansted, Luton and London City are all served and the transfer across the city can take longer than the flight.
• On low-cost tickets, add the cost of a checked bag and seat selection before you compare the totals.
• If your itinerary connects, make sure both legs sit on one ticket so a delay does not leave you stranded.
• Carry a valid passport or identity card for Luxembourg, and check the entry rules that apply to your nationality.
• Fly in October if the fare matters most, and book early for summer and the December holidays.
